Tabular Form - Read only condition for certain users

Question

Is it possible to make a select list field in a tabular form read-only to certain users? Here's the situation:
The tabular form lists the users who need to select "Approve" or "Reject" in that field (they are approving or rejecting an engineering change)
I want all of them to see the approval/rejection of their team, but only have access to edit the select list associated with their record.
Thanks in advance.

You could use either "authorisations" tab or "conditional display" for the relevant column attribute.
Report Attributes->Column Attributes->authorisationsIt would be better to have some more detail about what you are trying to get (maybe a quick mock up of the form, for example) but, I can envision something along the lines of the following:
For each approval/rejection field:
1. Create an authorisation appropriate for access to to each approval/rejection field e.g. authorisation scheme "FOO"
2. In the relevant fields column attributes, set the authorisation to "FOO"
3. now create a read only "public" copy of the above field, using the "display as text (based on LOV does not save state)" - set the authorisation for this field as "{NOT FOO}"
(if you don't want to use authorisations, you could build an equivalent using "conditional display" instead, which is basically the same thing, except column specific)
The downside is of course that you're duplicating fields in your query, which creates a bit of redundancy. There may be better ways to achieve this (maybe you could make use of the APEX_ITEM api, for example) but this is fairly easy to set up IMO.
